Problems solved by technology

[0008] In order to overcome the deficiencies of the prior art, the present invention provides a method for solving the limitation of data packet Ethernet encapsulation under U-CON active mode. In the active mode of U-CONOPCServer, the virtual serial port is used as the driver interface, and the underlying driver of the active non-standard device is compiled, which solves the problem that the communication data packets of such devices cannot be displayed on the U-CONOPCServer after being encapsulated by Ethernet. The limitation of data collection under the active mode of the present invention, the hardware configuration of the inventive method is simple, cost-effective, and the software driver development is convenient and quick

Embodiment Construction

[0044] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with specific examples.

[0045] Attached below Figure 1-4 The present invention is further analyzed.

[0046] The method for solving the limitation of data packet Ethernet encapsulation in a U-CON active mode of the present invention adopts configuring the Ethernet end of the serial device networking server as a virtual COM port, and links the virtual COM port in the active mode of U-CONOPCServer way to solve it. The specific implementation method is mainly divided into two steps: serial device network server module configuration, active mode underlying driver configuration, the steps are as follows Picture 1-1 and 1-2.

[0047] The configuration method of the serial device networking server module is described in detail as follows:

[0048] (1) Physical hardware connectio...

Abstract

The invention relates to a method for solving a data packet Ethernet packaging restriction under a U-CON active mode. The method employs a mode of configuring an Ethernet end of a serial port equipment networking server to be a vertical COM port and linking the virtual COM port under an active mode of a U-CON OPC Server; the method is specifically divided into two portions, i.e., serial port equipment networking server module configuration and active-mode bottom-layer driving configuration; the serial port equipment networking server module configuration comprises physical hardware connection, physical serial port configuration, physical net port configuration, configuration of mapping a net port to a serial port, and configuration change application; and the active-mode bottom-layer driving configuration comprises physical hardware connection, U-CON channel configuration, U-CON equipment configuration, U-CON driving configuration, and debugging and application. The method has the following advantages: the hardware configuration is simple, and the cost performance is high; and software driving development is convenient and fast, and transparent data access between a host computer and an active non-standard serial port device is realized.

Description

technical field [0001] The invention relates to a method for solving the problem that the serial port data cannot be collected in the OPCServer through the Ethernet communication mode in the active mode of the U-CON, which is developed by the underlying communication driver of the non-standard equipment in the foundry industry, and specifically relates to a U-CON A workaround for packet Ethernet encapsulation limitations in aggressive mode. It belongs to the field of communication. Background technique [0002] At present, U-CONOPCServer is often used in the development of the underlying driver of industrial non-standard equipment. It is only necessary to specify the communication protocol corresponding to the target device and the data that OPC needs to have access rights. With this tool, OPC standard drivers can be quickly developed to enable process control data to be exchanged smoothly between OPC compatible applications and any device that supports serial ports or Ethe...
